Intel CEO Paul Otellini on Windows 8 x86 and Windows 8 ARM: "We have the advantage of the incumbency, advantage of the legacy support. Not just in terms of applications but devices."

yeah using windows programs with touch might not be the best experience but this is not the same as old tablets where the os was just the standard windows xp with touch input added on top, it's an os optimized for touch input where you can even run legacy applications, if you need them.
For example let's say that vmware doesn't make a metro vsphere client, you can just use the windows one
